MECHANISM FOR ADJUSTING PAPER UPON FEED-BOARDS.

Specification of Letters Patent.

Application filed. November 27, 1916. Serial No. 133,761.

as are employed in connection with paper folding machines, printingpresses, etc, and has for its object the provision of means for changingthe position of sheets or lifts of paper upon the feed boards.

In my invention I employ roller mechanism operating to impart or permitmovement of a sheet or lift of paper longitudinally of the feed board,this roller mechanism desirably including a plurality of rollers havingparallel axes of rotation that are at right angles to the general lineof travel in which the paper is being fed. 7 The sections of the feedboard intervene between the rollers and extend beyond the first and lastrollers, the rollers preferably permanently projecting slightly abovethe station ary supporting surface of the feed board to have tractiveengagement with the sheets or lifts.

I will-explain my invention more fully by reference to the accompanyingdrawing showing the preferredembodiment thereof and in which Figure 1 isa plan view of a feed board equipped with my invention and shown inassociation with an impression cylinder of a printing press, parts beingbroken away; Fig. 2 is a view on line 22 of Fig. 1; Fig. 3 is a detailview of some of the parts as they appear in Fig. 2 taken on the line 33of Fig. 1; and Fig. 4 shows a detail of construction taken on the line4.4 of Fig. 1.

Like parts are indicated by similar characters of reference throughoutthe different figures.

The drawing shows the association of a feed board equipped with myinvention with a printing press (of which a printing cylinder 1 is shownin Figs. 1 and 2) butthe invention is not to be limited to suchassociation.'

The front division'2 of the feed board is the feeding end thereof fromwhich the sheets of paper are delivered singly to be operated upon bythe mechanism to which they are to be fed such as a printing press. Therear division of the feed board is preferably made up of sections 2 thattogether support the lift of paper indicated at 3 in Fig. 2, the sheetsbeing led from the lift or pile of paper 3 to the front or feedingportion of the feed board. The forward division of the feed board iscustomarily hinged at 4. The lift supporting portion of the feed boardis mainly the rear division,

a portion of the lift usually being also carried upon the rear part ofthe feed board division 2. The rear division of the feed board isequipped with rollers 5 that project sufliciently above the papersupporting surfaces of the feed board sections 2 which surfaces lie inthe same plane with each other and with the balance of the board. Therear portion of the forward feed board division 2 that takes part insupporting the lift is formed in sections 6, similar to sections 2 andis equipped with rollers 7 that project above the paper supportingsurface of the feed board to the same extent as the rollers 5. Therollers 5 and 7 are preferably limited in movement longitudinally of thefeed board. While I preferably form the feed board in sections 2 and 6for the purpose of enabling the rollers 5 to project above the papersupporting surface of the feed board, I do not wish to be limited tothis arran ement for enabling the projection of the ro lers above thefeed board nor to the complete separation of the sections 2 -and 6 whichI have illustrated for the purpose of accommodating the rollers.

As illustrated, the rollers 5 and 7 are re ceived in slots that extendclear across the feed board and which'slots are due to the formation ofthe feed board in sections 2 grooves 8 or other spaces in the rollers 5and 7 that subdivide the rollers into spaced apart paper supportingsections, and form' the sections 2 and 6 with noses 9 or othercontinuations that enter said grooves or spaces. These grooves aresufliciently deep to enable the ends of the noses or continuations 9 tobe positioned within the circles of the rollers, the noses terminatingslightly below the paper supporting surfaces of the a from passingthrough the roller containing slots. Each groove 8 desirably receives afeed board whereby they prevent the paper nose 9 upon each side of theroller having such groove so that the entry of the paper into a slot ateither side of the roller is guarded against. To prevent the sheets frombeing caught in the rollers when the sheet are moved crosswise of theboard, I roundthe 'roller's'ec'tions at the ends thereof which areadjacent the grooves 8. All of the rollers 5 upon the rear division ofthe feed board are preferably equipped with roller driving mechanism.The rollers 7 upon the front division of the board may be idle rollersor they may also be driven if preferred. The driving mechanismillustratedcomprises sprocket pinions 10 located upon one side of thefeed board and fixed upon theadj'acent ends of the shafts 11 that carrythe rollers 5. An endless sprocket chain 12 passes over thetopsof'thes'e-pinions and is maintained in engagement with the teeth ofthese pinions by means of the guard plate 13, this chain beingmaintained sufficiently taut by means of the idler sprocket 14: whichmay be adjusted up or down by the bolt and slot anchorage 15 for thebearing 16 of the wheel 14. The end of one of theshafts 11 that carriesa sprocket pinion 10 is desirably equipped with a hand crank 17, or anyother means for furnishing power, the shaft 11 selected for theattachment of the crank 17 thereto being desirably that upon which therearmost roller 5 ismounted. The foremost roller 5 desirably also has acrank 18 or some other suitable means for furnishing power connectedtherewith, the crank 18 being located on the side of the feed boardwhich is opposite to that upon which the crank 17 is located. By meansof either crank 17 or 18 the sprocket pinion 10 rigid with respectthereto may be turned to cause the travel of the endless sprocket chainand the simultaneous and synchronous rotation of the rollers 5.As'illustrated in Fig. 1, the rollers 7 are not equipped with anydriving pinions but in Fig. 2 the sprocket chain 12 is indicatedby'dotted lines 12 as being extended to have driving 'connection withthe rollers 7 similar to its driving connection with the rollers 5. v

To prevent'any of the rollers 5 from be- V ing turned by the shaking ofthe machine or the action of the lift-thereupon and thereby causeundesirable movement of the paper upon the same, I employ a suitablebraking device, one form of braking device being illustrated in Figs.land 2 where I have shown a braking clamp 18 embracing the shaft 11 ofthe foremost roller 5 and com- .prising two jaws hinged together at oneend of the clamp and coupled at the other end of the clamp by means ofan adjusting wing screw 20. The braking clamp is so adjusted that theshafts 11 may be turned notwithstanding the brakingac'tion of the clamp,

vent the rollers from turning due to the ment of an entire lift of paperby means.
